Explanation =========== If this :py:class:`~.PolyElement` belongs to a ring of $n$ variables, we can try to write it as a function of the elementary symmetric polynomials on $n$ variables. We compute a symmetric part, and a remainder for any part we were not able to symmetrize. Examples ======== >>> from sympy.polys.rings import ring >>> from sympy.polys.domains import ZZ >>> R, x, y = ring("x,y", ZZ) >>> f = x**2 + y**2 >>> f.symmetrize() (x**2 - 2*y, 0, [(x, x + y), (y, x*y)]) >>> f = x**2 - y**2 >>> f.symmetrize() (x**2 - 2*y, -2*y**2, [(x, x + y), (y, x*y)]) Returns ======= Triple ``(p, r, m)`` ``p`` is a :py:class:`~.PolyElement` that represents our attempt to express *self* as a function of elementary symmetric polynomials. Each variable in ``p`` stands for one of the elementary symmetric polynomials. The correspondence is given by ``m``. ``r`` is the remainder. ``m`` is a list of pairs, giving the mapping from variables in ``p`` to elementary symmetric polynomials. The triple satisfies the equation ``p.compose(m) + r == self``. If the remainder ``r`` is zero, *self* is symmetric. If it is nonzero, we were not able to represent *self* as symmetric.

The pseudo-division algorithm is used to find the pseudo-quotient ``q`` and pseudo-remainder ``r`` such that ``m*f = g*q + r``, where ``m`` represents the multiplier and ``f`` is the dividend polynomial. The pseudo-quotient ``q`` and pseudo-remainder ``r`` are polynomials in the variable ``x``, with the degree of ``r`` with respect to ``x`` being strictly less than the degree of ``g`` with respect to ``x``. The multiplier ``m`` is defined as ``LC(g, x) ^ (deg(f, x) - deg(g, x) + 1)``, where ``LC(g, x)`` represents the leading coefficient of ``g``. It is important to note that in the context of the ``prem`` method, multivariate polynomials in a ring, such as ``R[x,y,z]``, are treated as univariate polynomials with coefficients that are polynomials, such as ``R[x,y][z]``. When dividing ``f`` by ``g`` with respect to the variable ``z``, the pseudo-quotient ``q`` and pseudo-remainder ``r`` satisfy ``m*f = g*q + r``, where ``deg(r, z) < deg(g, z)`` and ``m = LC(g, z)^(deg(f, z) - deg(g, z) + 1)``. In this function, the pseudo-remainder ``r`` can be obtained using the ``prem`` method, the pseudo-quotient ``q`` can be obtained using the ``pquo`` method, and the function ``pdiv`` itself returns a tuple ``(q, r)``. Parameters ========== g : :py:class:`~.PolyElement` The polynomial to divide ``self`` by. x : generator or generator index, optional The main variable of the polynomials and default is first generator. Returns ======= :py:class:`~.PolyElement` The pseudo-division polynomial (tuple of ``q`` and ``r``). Raises ====== ZeroDivisionError : If ``g`` is the zero polynomial.

Examples ======== >>> from sympy.polys import ring, ZZ >>> R, x, y = ring("x, y", ZZ) >>> f = x**2*y + x*y >>> g = x + y >>> f.subresultants(g) # first generator is chosen by default if not given [x**2*y + x*y, x + y, y**3 - y**2] >>> f.subresultants(g, 0) # generator index is given [x**2*y + x*y, x + y, y**3 - y**2] >>> f.subresultants(g, y) # generator is given [x**2*y + x*y, x + y, x**3 + x**2] rrr)r9rrrrrry)rrrrzrHrSrdrrrAlcrTSrr3rs r8 subresultantsPolyElement.subresultants siD  FFLLO HHQK HHQK 5qq 6q6M 6q6M F E QUO FF1L E[[  G F B A HHQKqa%JA!af Aq A AQ"B1uSQJa%LGGAJC HHaRL'a*r:c8URRX5$r[)r9dmp_half_gcdexrMs r8 half_gcdexPolyElement.half_gcdex svv$$Q**r:c8URRX5$r[)r9 dmp_gcdexrMs r8gcdexPolyElement.gcdex vv%%r:c8URRX5$r[)r9 dmp_resultantrMs r8 resultantPolyElement.resultant svv##A))r:c8URRU5$r[)r9dmp_discriminantrs r8 discriminantPolyElement.discriminant svv&&q))r:cURR(aURRU5$[S5e)Nzpolynomial decomposition)r9r) dup_decomposer%rs r8 decomposePolyElement.decompose s0 66  66''* *-.HI Ir:cURR(aURRX5$[S5e)Nzshift: use shift_list instead)r9r) dup_shiftr%rzrqs r8shiftPolyElement.shift s0 66  66##A) )-.MN Nr:c8URRX5$r[)r9 dmp_shiftrs r8 shift_listPolyElement.shift_list rr:cURR(aURRU5$[S5e)Nzsturm sequence)r9r) dup_sturmr%rs r8sturmPolyElement.sturm s0 66  66##A& &-.>? ?r:c8URRU5$r[)r9 dmp_gff_listrs r8gff_listPolyElement.gff_list vv""1%%r:c8URRU5$r[)r9dmp_normrs r8normPolyElement.norm svvq!!r:c8URRU5$r[)r9 dmp_sqf_normrs r8sqf_normPolyElement.sqf_norm rr:c8URRU5$r[)r9 dmp_sqf_partrs r8sqf_partPolyElement.sqf_part rr:c4URRXS9$)N)rf)r9 dmp_sqf_list)rzrfs r8sqf_listPolyElement.sqf_list svv""1"..r:c8URRU5$r[)r9dmp_factor_listrs r8 factor_listPolyElement.factor_list svv%%a((r:)rr9r[)F)rrKrLrMrNrVr^rrcrrrrrprtrsrrrrrrrrrrrrrrr9rrr]rPrrrrrrrrrrrrr rrrr!r$r'r,r*r2r1r=r7rHrGrFrErbr^rkrjrsrvrzrrrrrirqryrrrrrrrrrrrrrrrrrPrrorr rfrrrrTrrrrrrr_r$r(r`r-r3r6r:rDrGrrrLrPrQrRrcrbrorkrurQrxrrr?rrrrrrrrrrrrrrrrrrrrrR __classcell__)rs@r8rrJsU?
